1. INTRODUCTION
The MCT-241 MD is a miniature, microprocessor-controlled personal
UHF transmitter. It is designed to transmit coded alert signals
manually (when the user presses the button) or automatically (when
the user falls down). The transmitter is waterproof and suitable for
wearing in a shower. Operating power is obtained from an internal 3V
CR-2 Lithium battery.
Transmission is initiated in the following cases:
Depressing the recessed oval pushbutton (see Fig. 1). A built-in
timer determines the transmission time to 3 seconds, even if the
user maintains the button pressed shorter or longer than that.
Tilting the transmitter by more than 60° in any direction. In this
case, the 3-second transmission will take place after a 2- second
delay.
When triggered, the MCT-241 MD transmits a unique 24-bit digital ID,
randomly selected in the factory. This code is one of 16 million possible
code combinations and is therefore virtually impossible to reproduce.
The ID code is followed by the appropriate digital marker that indicates
an “alarm” or a ‘fall-detector” event, as the case may be.
A red LED (see Fig. 1) lights steadily during transmission, to reassure
the user that a transmission is taking place and to indicate that the
battery condition is good. If the LED flashes each time the transmitter
is triggered, this indicates that the voltage is low and the battery must
be replaced as soon as possible.
If the transmitter is triggered while the battery voltage is low, a ‘low
battery’ digital marker is included in the transmitted message. In
addition, the battery is self-tested every 12 hours. A supervisory ‘low
battery’ message is transmitted after detection of 3 consecutive “low
battery” states.
The transmitter case is waterproof, hermetically sealed (no screws) and
therefore disposable. Do not attempt to open the transmitter case or
replace the battery; such action will void the warranty.
The transmitter is supplied with two wearing accessories, a neck cord
(to be worn around the neck - see Fig. 2) and a clip (to be attached to
the user belt or shirt pocket - see Fig. 3).
The neck cord includes a built-in safety release mechanism. This neck
cord must never be replaced with a cord that does not include a safety
release.
2. OPERATION AND ENROLLMENT
2.1 Transport Mode
New MCT-241 MD units are shipped with the tilt (fall-detector)
function in ‘deep sleep”, to prevent inadvertent transmissions until the
unit is placed into service. To ‘awaken” the tilt function, the alarm
pushbutton must be pressed at least 5 times in succession
.
2.2 Tilt Alarm/Tilt Restore
A built-in tilt sensor is activated once the unit is tilted over by more than
60° in any direction. The Base Unit will notify the user after 30 seconds,
and the actual tilt alarm transmission to the central station will take
place after an additional 30-second delay, throughout which the unit
may be restored to the upright position. This allows the user to prevent
an accidental “tilt alarm” message from being transmitted. If a tilt alarm
had been transmitted and the unit was subsequently returned to the
upright position, a “tilt restore” message will be transmitted.
Note: Please refer to the AMBER user manual for further details on
this feature.

2.3 Low Battery Voltage Indication
The battery is automatically tested under load once in 12 hours. If a
low battery state is registered in 3 consecutive tests, a “low battery”
message will be transmitted, and a “low battery” digital marker will be
included in every transmission, “alarm” or “tilt”. In addition, when the
battery voltage is low, the LED flashes while the pushbutton is
pressed.
2.4 Transmitter Stand
When putting the transmitter away, it is recommended to use the
special stand included in the package (Fig. 5). The stand will maintain
the unit in a vertical (upright) position, thus preventing accidental
activation of the tilt sensor. Place the stand on a flat surface, then
insert the bottom end of the unit into the stand.
